Combustor and gas water heater with combustor

Abstract

The invention discloses a combustor and a gas water heater with the combustor. The combustor comprises fire grates. A mixing cavity is limited in each fire grate, and the fire grates are provided withgas inlets communicating with the mixing cavities, main gas outlets and auxiliary gas outlets. Each fire grate comprises a first sheet, a second sheet and a partition plate. Each second sheet and thecorresponding first sheet are arranged oppositely and define the corresponding mixing cavity. Each partition plate is arranged between the corresponding first sheet and the corresponding second sheet, the two sides of each partition plate are connected with the corresponding first sheet and the corresponding second sheet respectively, the main gas outlets are formed on the partition plates, and the auxiliary gas outlets are defined by the partition plates and at least one in the first sheets and the second sheets. According to the combustor disclosed by the embodiment of the invention, the auxiliary gas outlets located on one sides of the main gas outlets are defined by the partition plates and at least one in the first sheets and the second sheets, the area of the gas outlets can be increased, heat loads can be improved, and the quality and the use index of the gas water heater can be improved easily.

Description

technical field [0001] The present invention relates to the technical field of water heaters, more specifically, to a burner and a gas water heater with the same. Background technique [0002] The burner is an important part of the gas water heater. In the related art, the fire hole of the horizontal ejector fire row of the burner usually adopts a group of neatly and evenly arranged slit fire hole structures every four long holes, and the flow channel structure size of the burner In terms of design, there are also some resistances to gas flow. The above structure will lead to problems such as low heat load of the burner and poor flame uniformity. It is necessary to improve it. Contents of the invention [0003] This application is based on the inventor's discovery and recognition of the following facts and problems: [0004] The flame hole of the burner in the related art adopts a multi-group neatly and evenly arranged strip-shaped hole structure. Multiple groups of str...

AI Technical Summary

Problems solved by technology

Multiple groups of strip holes are arranged on the U-shaped sheet of the burner. When the gas in the mixing chamber flows out through the hole adjacent to the side of each strip hole, there is a certain resistance, which easily leads to a low heat load of the burner. , poor flame uniformity, etc.
